David Raker has made a career out of finding the lost. Enlisted by Sam's desperate wife, Raker must unearth secrets that go deeper than anyone could have imagined if he hopes to find Sam. Someone knows what happened on the tube that day, and they'll do anything to keep Sam's secrets firmly buried . . .
